MATERIAL KNOWLEDGE / SOCKET WELD FITTINGS
Titanium’s corrosion behaviour is closely linked to its protective oxide film. Suitability depends on the selected material and the actual chemical environment.
MATERIAL EXPLORER / Ti
Explore three views of the material. These diagrams explain relationships; they do not represent a measured microstructure or predict performance.
Surface film
An adherent oxide film forms at its surface and helps protect the metal beneath. Environments that maintain this film support its corrosion resistance.
The exact material and its condition remain part of the complete technical description.
Environment
Some conditions maintain the protective film, while others attack it. The process medium, concentration, temperature and contaminants can therefore change corrosion behaviour.
The exact material and its condition remain part of the complete technical description.
Service context
Material selection must consider the process medium, concentration, temperature and contaminants. General corrosion-resistance descriptions should not be treated as permission to use titanium in any chemical service.

01 / MATERIAL OVERVIEW
Titanium forms an adherent oxide film that protects it in many environments. Conditions that maintain this film support corrosion resistance; conditions that attack it can produce very different behaviour.
Material selection must consider the process medium, concentration, temperature and contaminants. General corrosion-resistance descriptions should not be treated as permission to use titanium in any chemical service.
General background for the explanation above. The project specification governs the actual selection.
02 / MATERIAL KNOWLEDGE
Titanium forms an adherent oxide film that protects the underlying metal in many environments. Its corrosion behaviour changes when conditions maintain or attack that film. Understanding this surface mechanism explains why a general corrosion-resistance description cannot describe titanium’s behaviour in every chemical environment.
Titanium is protected by an oxide film; stainless steel forms a chromium-rich passive film. Both mechanisms depend on the material and environment, so a protective surface film does not imply identical corrosion behaviour.

Some conditions maintain the protective film, while others attack it. The process medium, concentration, temperature and contaminants can therefore change corrosion behaviour.
03 / SELECTION CONSIDERATIONS
Provide the complete service description, including relevant impurities and operating conditions.
Identify the specified titanium grade and applicable material requirements.
Include fabrication, inspection and documentation requirements for confirmation of supply availability.
04 / FROM MATERIAL TO FITTING
Titanium is considered for corrosion-related engineering requirements where its behaviour has been assessed against the intended environment.
